Yakov, the p'd-off unicorn

Excuse the abbreviated title, but I feel like being too careful. His alternate name is Giacomo, and they both mean 'supplanter'. Yes, he's the bad guy that Kaida was sent to kill. He's a fallen ascended - a unicorn, actually - and he's powerless without his horn, which the satyr Rowdy stole from him. The chair? I have no clue. I just felt like drawing a prop. Oh, and on the original I had a note that said 'for lack of a better costume'. I'll think up a better one later.
